Java GrailsXML到对象绑定

是否有grails插件或库可以将XML数据映射到Java类对象

我正在寻找一些将xml数据映射到Java类字段的groovy类

---更新-----

下面的grails服务类尝试进行此映射，但不起作用

有人会给出提示如何更正下面的代码以使其正常工作吗

谢谢

Groovy的

XMLSlurper

还不够？它不是通用的。我们需要手动解析xml并保存到Java对象。正当我需要的是一个通用方法来自动绑定一个java类和xml数据。我已经更新了OP。我尝试绑定一个类。但它不起作用。你可以使用Xstream来实现。检查这篇文章我写的这篇文章真的很好。正是我想要的。我要试试XStream。谢谢
